ABSTRACT
BACKGROUND AND OBJECTIVES: Head, face and neck pain affects a large portion of the world population, however there are few studies reporting this condition in general Brazilian population. This study aimed at investigating the prevalence of head, face and neck pain and its impact on the quality of life of adults of Piracicaba city, São Paulo. METHODS: The sample was made up of 400 volunteers of both genders, aged between 20 and 50 years, who were randomly approached in six crossing points of the city. Socio-demographic, pain prevalence, location, frequency, duration and severity, and self-perception of quality of life data were collected by means of anonymous self-applied questionnaires: Orofacial Pain Questionnaire and WHOQOL-BREF. RESULTS: Pain prevalence was 54.75%, of predominantly severe intensity (21.30%), daily recurrence (41.10%) and present for more than six months (91.32%). Most affected region was the head (36%) being the intraoral region the less frequently reported (6%). There has been no significant association between pain and factors such as age, economic level and education (p>0.05); however there has been significant prevalence among females. No pain was frequently associated to better quality of life (p<0.05). Volunteers reporting pain were more unhappy with quality of sleep (p<0.05), however there has been no significant association with the frequency of negative feelings. CONCLUSION: The study has identified high prevalence of head, face and neck pain, significant morbidity of people affected by this condition and its negative impact on quality of life. .
JUSTIFICATIVA E OBJETIVOS: As dores que acometem o segmento cefálico afetam grande parte da população mundial, porém são poucos os trabalhos que retratam essa condição na população geral do Brasil. O objetivo deste estudo foi investigar a prevalência de dor no segmento cefálico e seu impacto sobre a qualidade de vida de adultos do município de Piracicaba, São Paulo. MÉTODOS: A amostra foi composta por 400 voluntários de ambos os gêneros, com idade entre 20 e 50 anos que foram aleatoriamente abordados em seis pontos de passagem do município. A coleta de dados sócio-demográficos, prevalência, localização, frequência, duração, gravidade da dor e autopercepção da qualidade de vida foi realizada por meio de questionários anônimos autoaplicados, o Questionário de Dor Orofacial e o WHOQOL-BREF. RESULTADOS: A prevalência de dor foi de 54,75%, de intensidade predominantemente intensa (21,30%), recorrência diária (41,10%) e presente há mais de seis meses (91,32%). A região mais acometida foi a cabeça (36%) sendo a região intraoral menos frequentemente apontada (6%). Não se observou associação significativa entre a presença de dor e fatores como idade, nível econômico e escolaridade (p>0,05), porém houve significativa prevalência de dor entre as mulheres. A ausência de dor foi frequentemente associada à melhor qualidade de vida (p<0,05). Voluntários que relataram dor apresentaram maior insatisfação com a qualidade do sono (p<0,05), porém não foi observada associação significativa com a frequência de sentimentos negativos. CONCLUSÃO: O estudo identificou alta prevalência de dor no segmento cefálico, significante morbidade das pessoas acometidas por essa condição e seu impacto negativo sobre a qualidade de vida. .
ABSTRACT
Aim: The aim of this study was to investigate mean electrical activity and how the anterior, middle, and posterior portions of the temporalis muscle work during mastication. Methods: The sample consisted of 16 healthy male college freshmen trichotomized, aged between 18 and 25 years, with Angle's Class I and no temporomandibular disorders. Electromyographic (EMG) recordings were made in anterior, middle and posterior portions of the temporalis muscle during mastication for 5 s. Results: It was found a significantly lower RMS value in the posterior portion (RMS: 1243.92) compared with those of the anterior (RMS: 2149.77) and middle (RMS: 2531.38) portions. Conclusions: There is an association between the portions of the temporalis muscle. It was found a significantly lower RMS value in the posterior portion showing that the anterior and middle portions of the muscle have a predominant function of maintaining movement during mastication.

Aim: To describe the characteristics of the professional training of dentists and physicians who treat patients with pain. Methods: A sample of 87 dentists and 63 physicians, selected at random and based on a stratified strategy, responded to a questionnaire with questions about training in pain. The statistical analysis of the data was done by the chi-square test and the Students t-test at a 5% significance level. Results: The mean age was 45 years. There was no gender prevalence among the dentists and a male predominance among physicians; 80.20% had worked professionally for more than ten years; 81.61% of the dentists and 79.37% of the physicians were specialists. Residence training was reported by 55.56% of the physicians and 12% of the dentists; 48.27% of the dentists and 34.92% of the physicians had a masters and/or doctorate degree; 69.33% declared sufficient knowledge in pain; both physicians and dentists prioritized their own areas regarding the study of pain. The doctor/patient relationship was more valued by physicians, while the technical training was more valued by dentists. Dentists reported more difficulties in prescribing medications and physicians had more difficulties with the patients behavior. Conclusions: Dentists and physicians had different professional experience and had valued specific aspects of their specialty. There is a need for a uniform curriculum designed for training in pain.

O objetivo deste trabalho foi verificar a validade na utilização da Eletromiografia como ferramenta de diagnóstico e avaliação dos tratamentos com Ortopedia Funcional dos Maxilares, em pacientes portadores de maloclusões.. Foram selecionados 19 voluntários de ambos os sexos, que foram submetidos à avaliação eletromiográfica bilateral dos músculos temporal porção anterior, masseter e supra-hioideos, em repouso, oito minutos após instalação do aparelho ortopédico funcional, e quando a relação de incisivos em D.A. foi constatada. Os dados eletromiográficos foram coletados utilizando o módulo condicionador de sinais com oito canais, modelo EMG 1000, e analisados com o Software AqDAnalysis 4,18 da Lynx Electronics Ltda.. Os tratamentos foram efetivados com aparelhos ortopédicos funcionais bioplásticos e bioelásticos. Os resultados permitiram concluir pela validade da aplicação da Eletromiografia tanto no diagnóstico, como na avaliação dos estados referentes ao sistema neuromuscular resultantes de tratamentos de maloclusões com a Ortopedia Funcional dos Maxilares.
The main objective of this work was to verify the validity of Electromyography use as a tool for diagnosis and evaluation of Functional Maxillary Orthopedics malocclusion treatments. Nineteen individuals were selected from both sexes, and submitted to bilateral electromyographic evaluation from anterior temporalis, masseter and suprahyoids muscles in rest, eight minutes after functional orthopedic appliance installation and when D.A. incisors relationship were gained. The electromyographic data were collected using signal conditioner module with eight channels, EMG 1000 model, and analyzed with AqDAnalysis 4,18 from Lynx Electronics Ltd. The malocclusion treatments were done with bioplastics and bioelastics functional orthopedic appliances. The results permit concludes that Electromyography is a trustable tool to be used in Diagnosis and in evaluation of neuromuscular system results from malocclusions treatments with Functional Maxillary Orthopedics.
